Yellow06CobaltSS

I have an "06" Chevy Cobalt SS. Last summer, I had my ignition switch replaced due to the recall. The day after, my electronic locks, windows & mirrors stopped working. I called up the dealership, explained this didn't happen before they replaced my ignition switch, they tested it, everything came back normal. once I got home, they still Wernt working so I took the door panel off, checked it out, nothing... a day later, they started working like normal again. This has happened a handful of times and I'm not sure what is going on. any ideas On what's wrong?
